This document discusses how the SEASR project provides analytics services for Zotero collections. SEASR offers authorship analysis like author centrality, degree, and HITS analysis on Zotero collections. It also provides readability analysis. Users can store and share Zotero collections via Fedora using SEASR. The services are accessed through an interactive web application or web service. SEASR and its Meandre infrastructure are sponsored by The Andrew W. Mellon Foundation.

4. Some Examples
• Authorship Analysis
• Author Centrality Analysis
– Uses Betweenness Centrality, which ranks each coauthor graph derived from the
number of shortest paths that pass through them
• Author Degree Analysis
– Uses AuthorDegreeDistributionAnalysis, which ranks each on the number of coauthors
• Author HITS Analysis
– The *hubness* of a node is the degree to which a node links to other important
authorities. The *authoritativeness* of a node is the degree to which a node is pointed
to by important hubs.
– Readability
• Flesch-Kincaid readability test quot;
